With scientists sending space probes to the furthest reaches of the solar system and beyond, the scientific search for alien life has begun. Inspired by a childhood love of science fiction, Brian still hopes to hear from ET. He explains why this search deserves to be taken seriously, and he explores the chances of it happening.
Brian takes a fresh look at the concept of gravity, revealing it to be far more than just the force that makes things fall to the ground. Recent scientific breakthroughs are challenging physicists' ideas of the very nature of reality. He recalls some of his most iconic TV moments: being first on the scene to meet a space capsule returning three astronauts from the International Space Station, and demonstrating how a bowling ball and feather fall at the same speed.
Brian explores a simple question that is causing a big stir today: what is time? Modern science shows it to be far stranger than we think. He recalls some highlights from his TV series that touch upon different sides of this physics conundrum.
Brian explores the latest science and takes a new look at his old films and asks how far humanity can go in their exploration of the cosmos. Brian begins in Russia's cosmonaut training facility in the outskirts of Moscow.
